The BRK 3120B smoke alarm is a 120 volt, dual detection smoke alarm that utilizes photoelectric and ionization sensors to detect a multitude of smoke types. The BRK photoelectric sensor is designed to identify larger smoke particles usually associated with smoldering flames, while the ionization sensor will detect minute particles as they spread through the house (or from smaller burning fires).
The BRK 3120B smoke alarm will provide detection quickly and will serve as you first line of defense. This state of the art BRK smoke alarm has several indicators based on its recent activity; an alarm latch which exposes to identify that it is the imitating alarm (if interconnected to other devices), as well as a battery latch which will be exposed when a new battery is needed. The backup batteries (2 x AA) inside the BRK 3120B will provide additional power if needed during power loss.
BRK 3120B smoke alarms meet all requires of UL217, CSFM, NFPA 72, HUD, FHA and other agencies requiring an AC/DC photoelectric ionization combination smoke alarm. In addition, the BRK 3120B incorporates BRK’s patented OptiPath technology designed to maximize effectiveness when mounted against a wall, or on a ceiling.
